My XH is on the birth certificate. Last Friday (DS birthday), he turned up at the school to give DS a present. Fortunately my cousin was there to collect him as usual. XH told the teacher who he was and then proceeded to lie and tell her I refused to let him see his son, that he wanted reports and parents meetings etc. On the way back to my cousin's, he told her what would happen if I die. On Sunday, I took DS to his father's. XH gave me a piece of cake and then asked if I liked it. I said yes and proceeded to tell me a friend made it to celebrate getting out of prison and how he wanted to go back in by killing someone. On Monday, he phoned the school and added himself to his emergency contact list. I don't know if he actually threatened me, if he's planning something or if he's messing with my head but I need to protect my DS.
